Simply by living, an 87.5 kg human being will consume approximately 20.0 mol of O 2 per day. To provide energy for the human, the O 2 is reduced to H 2 O duing food oxidation by the reaction O 2 + 4 H + + 4 e − − ⇀ ↽ − 2 H 2 O Determine the current generated by the human per day. In this case, the current is defined as the flow of electrons ( e − ) to O 2 from the food the human consumes.

Using the periodic table, complete the table to describe each atom. type in your answers.a ? b? c? d? e? f?

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
